A Westpac spokesman confirmed a small number of Westpac’s merchant customers were currently affected by an outage of a third-party app, which allowed a mobile phone to be used as a terminal to accept payments.
“The app’s developers are working urgently to address the issue, which is expected to be resolved later this afternoon,” the spokesman said.
“Westpac apologises to affected customers and the public who may be inconvenienced.”
It is the second time the bank has had to apologise to its customers in a week, after a technology glitch meant some transactions made on the busiest shopping days before Christmas were not processed correctly and only put through a fortnight later.
That issue has left some Westpac customers out of pocket and with transactions being declined, after they were accidentally sent into overdraft.
The Westpac spokesman said the app outage was unrelated to the earlier transaction processing issue, which affected Mastercard credit and debit transactions from December 22 and 23.
The retailer said he had also experienced intermittent issues with card payments before Christmas.
“The problem is when you have had it as an ongoing issue it starts to impact your brand because customers don’t realise necessarily that it is a bigger problem - they just see a retailer who can’t provide a basic part of the equation, and they just go somewhere else.”
He estimated over the trading period that he could potentially have lost thousands of dollars.
“For a small retailer - which is what I am - [that] is not insignificant. Any dollar that goes out the door is a dollar that goes out the door and potentially a customer that may or may not come back.”
